Vicious Machete Attack in New Jersey Caught on Tape

Police in Paterson, New Jersey announced on Wednesday that they'd arrested three men wanted for viciously assaulting two men with a machete inside a restaurant back in September. How'd they do it? They posted the surveillance footage on Facebook in an effort to crowdsource the investigation.

Sure enough, it worked. One suspect "turned himself in because he felt all this pressure from everywhere," explained one police official. The security camera footage that the Paterson cops released is above. Do be warned, though: It's pretty graphic and not for the faint of heart. [CBS New York]
